Manufacturer: Waveshare
Compatibility: Raspberry Pi


The module allows to control the actuators consuming the current of up to5 A using microcontroller's ports or any development kit (includingArduino,Raspberry PiandSTM32Discovery).Optoisolation seperates the control signal from the part associated with the power of relay, thereby providing work safety of the system management. Board has been adapted to work withthe Raspberry Pi A+/B+/2B/3B/3B+as HAT shield,it also has a case with bracket for mountingon a DIN railanda set of spacers and screws. The manufacturerprovides the instruction with examples of using wiringPi, bcm2835, python, python-bottle (control via the website) and crontab.


For proper operation, it is sufficient to connectthe Raspberry Pito the slot for the GPIO pins. Pins are the standard ARK screw connection that enable the easy connection without soldering. In addition, it is possible to change the default control pins using jumpers. If necessary, you can cut the PCB at the specified place andturn it into a traditional module with relays without the HAT shield. In this case, you need to connect 5 V to the relay coils through ARK screw connection, the ground of the system GND and control pins to the connectors CH1 ... CH8.
